The Engineered Body

Bioengineering often connotes manipulations at the molecular level—creating, for example, genetically altered animals. But another side of this discipline deals with the visible and tangible, as scientists discover how to use modern materials and techniques in solving intractable medical conditions. Teams at Massachusetts General Hospital have pioneered synthetic joints that last for more than a decade without wear, refined software and implantable devices that coax the body into fabricating new bone, and helped paralyzed people learn to direct computers with their thoughts—a first step, perhaps, toward one day regaining control of their immobilized bodies.
